“I have utitlized Ted DeLong’s services at both my home and commercial business for over 15 years. He has always provided outstanding installation, service and efficiency strategies. With Ted’s expertise and knowledge of energy efficient systems, our savings go straight to the bottom line.”

“We were very pleased with the young man that put our HVAC in – they looked very nice. Someone you could trust in your house – In fact the first day I met them we had to go away and left the house for them to close up – because I really trusted them. Thanks.”

Best HVAC service provider I have ever experienced. Would not use anyone else. Best techs in the industry and very nice to deal with and have in your home. Most have been with the company for a long time so you get to know them. The owner is involved in major projects and makes sure the smallest of details are handled right. I have purchased two separate home HVAC systems from them and the install is done right the first time every time. I also have them service multiple commercial systems in addition to my home system. Competitive pricing and they sell you what you need, nothing more...nothing less.

It has been a pleasure working with Ted Delong and his company. They are knowledgeable, thorough and courteous. Hope to continue to work with them. John Harkleroad, Vice President Construction Operations Brentwood Builders, Inc.
